Summary of ChangesHello @leeroybrun, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces a crucial enhancement to the daemon's session management by enabling sessions to persist and be reattached after a daemon restart. It establishes a new disk-based session registry to store minimal session markers and full session states. This allows the daemon to automatically discover and adopt existing sessions on startup, and provides a new CLI command for users to manually resume specific sessions. The changes ensure a more resilient and seamless experience for long-running agent interactions, preventing loss of context due to daemon interruptions. Highlights

Code Review
This pull request introduces a robust mechanism for reattaching to sessions after a daemon restart, significantly improving the daemon's resilience. The implementation, particularly the use of atomic file writes for session state and session markers in sessionRegistry.ts, is well-executed. My review focuses on a few key areas: there's considerable code duplication in the session handling logic across the different agent runners (claude, codex, gemini), which I recommend refactoring. I've also identified a missing feature implementation in runGemini.ts and a minor typing improvement for better code safety.

The logic to parse the --resume command-line argument is missing here. This is inconsistent with runClaude.ts and runCodex.ts and is the first part of a bug that prevents resume functionality from working correctly for the Gemini agent.

After adding the parsing for vendorResume from the command-line arguments, you need to pass it here when persisting the session information to ensure the resume functionality works for Gemini.

This large block of code for handling session attachment and persistence is duplicated across runClaude.ts, runCodex.ts, and runGemini.ts. This duplication makes maintenance more difficult and increases the risk of introducing inconsistencies between the different agent startup implementations. In fact, this has led to the --resume feature being missed in runGemini.ts.
I recommend refactoring this logic into a shared function that can be called from each run file. This would centralize the session setup, improve maintainability, and ensure consistent behavior across all agents.

This block of code for session attachment and persistence is nearly identical to the one in runClaude.ts and runGemini.ts. As mentioned in the other file, this duplication should be addressed by refactoring the logic into a shared utility function. This will make the codebase easier to maintain and prevent inconsistencies.

The function resumeDaemonSession is typed to return Promise<any>. For better type safety and code clarity, you should define and use a specific type for the return value, based on the response schema defined in controlServer.ts.
| export async function resumeDaemonSession(sessionId: string): Promise<any> { | |
| const result = await daemonPost('/resume-session', { sessionId }); | |
| return result; | |
| } | |
| export async function resumeDaemonSession(sessionId: string): Promise<{ success: boolean; sessionId?: string; error?: string; }> { | |
| const result = await daemonPost('/resume-session', { sessionId }); | |
| return result; | |
| } |
- Parse --resume in gemini runner and persist vendorResume for reattach/resume - Type controlClient.resumeDaemonSession to match controlServer response schema (Gemini feedback on PR #4)

fs.writeFile(imported fromfs/promises) returns a Promise. Withoutawait, the file write may not complete before the process spawns, potentially causing the Codex agent to fail authentication.Proposed fix

🔇 Additional comments (34)
src/persistence.ts (3)
224-241: Robust retry logic for daemon state reads.The retry mechanism with a 15ms delay handles potential race conditions when the reader races with an atomic rename operation. The implementation correctly:
- Validates existence before attempting reads
- Retries up to 3 times on parse errors
- Logs errors only on the final failure attempt
247-255: Atomic write pattern correctly implemented.The write-to-temp-then-rename pattern ensures atomic updates on POSIX systems. Directory creation before write prevents failures on first run.
264-267: Good cleanup of temporary files.Removing leftover
.tmpfiles during cleanup prevents stale artifacts from accumulating if a previous write was interrupted.src/daemon/sessionRegistry.ts (6)
8-20: Well-defined schema for session markers.The Zod schema provides strong runtime validation. Using
z.any().optional()for metadata allows flexibility while still validating the core fields.
22-36: Persisted session schema captures all necessary state.The schema correctly captures encryption details, agent state, and vendor-specific resume data needed for session reattachment.
58-70: Session marker write correctly validates and enriches data.Using
DaemonSessionMarkerSchema.parse()ensures the payload is valid before writing. The timestamp defaults are appropriate.
81-104: Safety check for happyHomeDir prevents cross-environment marker leakage.Line 96 filters markers to only accept those matching the current home directory, preventing accidental adoption of markers from different environments.
106-134: Persisted session write is well-structured.The function correctly encodes the encryption key to base64 and validates the structure before writing.
136-147: Read function gracefully handles missing/invalid sessions.Returning
nullon parse failure or file read error is appropriate for this use case.src/daemon/controlClient.ts (1)
87-96: New resume client function follows established patterns.The
ResumeDaemonSessionResulttype clearly defines the response shape, and the function delegates todaemonPostlike other daemon client functions.src/index.ts (2)
300-324: Resume command correctly handles multiple session IDs with proper exit codes.The implementation:
- Validates at least one session ID is provided
- Iterates over all IDs and reports individual outcomes
- Exits with code 1 if any resume fails
- Handles both result errors and thrown exceptions
394-394: Help text updated to document the resume command.The documentation clearly explains the purpose of the resume command.
src/daemon/controlServer.ts (1)
173-198: Resume endpoint correctly maps all SpawnSessionResult cases.The handler maps all three result types:
success→ returns{ success: true, sessionId }requestToApproveDirectoryCreation→ returns error with directory infoerror→ returns error messageThe response schema at lines 180-184 correctly allows optional
sessionIdanderrorfields.src/codex/runCodex.ts (2)
124-138: Attach-or-create flow correctly integrated for Codex.The implementation correctly:
- Parses argv for existing session ID
- Uses
attachOrCreateHappySessionfor session creation/attachment- Logs whether session was attached or created
- Creates the sync client using
baseSession
154-160: Session persistence for daemon correctly configured.The
persistHappySessionForDaemoncall includes all required parameters. Note thatvendorResumeis not passed here, which is correct since Codex may not support vendor-specific resume (unlike Claude with--resume).src/claude/runClaude.ts (3)
102-116: Attach-or-create flow correctly integrated for Claude with vendor resume support.The implementation:
- Parses
--resumefrom argv viaparseVendorResumeFromArgv- Uses
attachOrCreateHappySessionfor session management- Logs the attach/create status
- Creates the sync client immediately using
baseSession
131-138: Session persistence includes vendor resume for Claude.Unlike Codex, Claude passes
vendorResumetopersistHappySessionForDaemon, enabling the daemon to restore the Claude--resumeflag when reattaching sessions.
145-149: SDK metadata update correctly uses session instance method.The callback correctly uses
session.updateMetadatato merge SDK capabilities into session metadata.src/gemini/runGemini.ts (4)
30-30: LGTM!Import follows the
@/alias convention and correctly imports the new session bootstrap utilities.
123-135: LGTM!The attach-or-create session flow is correctly implemented and aligns with the pattern used in
runClaude.tsandrunCodex.ts. The dependency injection wrapper aroundapi.getOrCreateSessionis clean.
139-144: LGTM!Session ID references are consistently updated to use
baseSession.idfor daemon reporting.
150-156: LGTM!The session persistence call correctly omits the
vendorResumeparameter sincevendorResumeSupportedForFlavor('gemini')returnsfalse. All required fields are properly passed.src/daemon/run.ts (7)
16-16: LGTM!Imports are correctly added for the new session bootstrap and registry functionality.
Also applies to: 21-21
145-172: LGTM!The session reattachment logic on daemon restart is well-implemented:
- Uses
process.kill(pid, 0)correctly to check if process is alive without signaling- Properly filters by
happyHomeDirto prevent cross-stack attachment- Cleans up stale markers for dead processes
- Logs the number of adopted sessions for observability
178-182: LGTM!Good safety check to ignore webhook reports from sessions belonging to a different
happyHomeDirstack.
220-228: LGTM!Writing the session marker after webhook enables future daemon restarts to reattach. The fire-and-forget pattern with
.catch(() => {})is acceptable here since stale markers are pruned by the daemon.
462-463: LGTM!Cleaning up the session marker when a child process exits ensures stale markers don't accumulate.
465-542: LGTM!The
resumeSessionfunction is well-implemented:
- Checks for already-tracked sessions and validates liveness
- Reads persisted session state and validates
happyHomeDirfor cross-stack safety- Correctly uses
vendorResumeSupportedForFlavorto conditionally include--resumeflag- Writes session marker immediately for reattachment resilience
- Properly registers exit/error handlers for cleanup
549-549: LGTM!The
resumeSessionfunction is correctly passed to the control server to enable on-demand session resumption.src/daemon/sessionBootstrap.ts (5)
1-4: LGTM!Clean imports using the
@/alias and a well-defined type for the supported agent flavors.
6-14: LGTM!Both argument parsers handle edge cases gracefully by returning
nullwhen the flag is present but the value is missing (argv[idx + 1]being undefined).
16-20: LGTM!Clear policy documentation for vendor resume support. The extensibility note for forks is helpful.
22-56: LGTM!The attach-or-create flow is well-designed:
- Uses dependency injection for testability
- Throws a clear error when attempting to attach to a non-existent session
- Correctly reconstructs the
encryptionKeyfrom base64 when attaching- Returns both the session and a flag indicating whether it was attached
58-96: LGTM!The persistence function is well-implemented:
- Respects flavor-based vendor resume policy
- Correctly orders operations: persist session data first, then write marker
- The
process.once('exit')cleanup is appropriately documented as best-effort since async operations may not complete during exit, and the daemon's adoption logic handles stale markers

mkdiruses{ recursive: true }, it's idempotent and won't throw if the directory already exists. The practical impact is minimal.♻️ Simplified idempotent version
async function ensureDir(dir: string): Promise<void> { - if (!existsSync(dir)) { - await mkdir(dir, { recursive: true }); - } + await mkdir(dir, { recursive: true }); }

**/*.{ts,tsx}: No untyped code - use strict typing in TypeScript with explicit parameter and return types
Use comprehensive JSDoc comments - each file includes header comments explaining responsibilities
ALL imports must be at the top of the file - NEVER import modules mid-code
Use named exports preferred, with occasional default exports for main functions
Avoid creating stupid small functions, getters, or setters - minimize unnecessary function decomposition
Avoid excessive use ofifstatements - especially if you can avoid control flow changes with a better design

src/**/*.{ts,tsx}: Use@/alias for src imports, e.g.,import { logger } from '@/ui/logger'
Use graceful error handling with proper error messages, try-catch blocks with specific error logging, and abort controllers for cancellable operations
All debugging must be through file logs to avoid disturbing Claude sessions - console output only for user-facing messages
Handle large JSON objects with truncation in logs to avoid excessive output

🔇 Additional comments (20)
src/codex/runCodex.ts (3)
31-31: LGTM!The import of
writeDaemonSessionMarkerForCurrentProcessaligns with the PR's goal to persist session markers for daemon reattachment.
124-128: LGTM!Clean refactoring to the
baseSessionpattern with immediatesessionSyncClientcreation. This ensures the session client is available early for background tasks.
143-149: LGTM!The session marker is correctly written after daemon notification with all required fields. The
startedByfallback to'terminal'is consistent with the type signature.src/claude/runClaude.ts (6)
27-27: LGTM!Import aligns with the new session marker persistence pattern.
102-106: LGTM!The refactor to create
baseSessionand immediately create the realtimesessionclient early is a good pattern. This ensures background tasks like SDK metadata extraction can use the session client.
120-126: LGTM!Session marker correctly written with the same pattern as Codex. Parameters are properly passed.
133-137: LGTM!Using
session.updateMetadatadirectly is correct since the session client is now created earlier. The callback pattern properly merges SDK metadata.
144-144: LGTM!The comment clarifies the flow - the session is already created above, preventing duplicate creation.
177-177: LGTM!Log correctly references
baseSession.idfor consistency.src/daemon/run.ts (5)
20-20: LGTM!Import of session registry functions aligns with the new reattachment feature.
144-171: Session reattachment logic looks correct.The implementation properly:
- Validates cross-stack safety via
happyHomeDircheck- Uses
process.kill(pid, 0)to verify process liveness- Removes stale markers for dead processes
- Avoids duplicate tracking via
pidToTrackedSession.has()check- Sets
startedByto'reattached'for adopted sessions (with nullish coalescing fallback to marker value)One minor observation: the
startedByassignment on line 159 usesmarker.startedBy ?? 'reattached'. Ifmarker.startedByis'daemon'or'terminal', it will preserve that value rather than marking it as'reattached'. This may be intentional to preserve original provenance.
177-181: LGTM!Cross-stack safety check correctly ignores webhook reports from sessions belonging to a different
happyHomeDir. This prevents a daemon from accidentally tracking sessions managed by another daemon instance.
219-227: Best-effort marker persistence is appropriate.The fire-and-forget pattern with
.catch(() => {})is acceptable here since:
- The marker write is supplementary for future reattachment
- Failure to write doesn't affect current session operation
- Silent catch avoids unhandled rejection warnings
461-461: LGTM!Marker cleanup on child exit with fire-and-forget pattern is appropriate. This prevents stale markers from accumulating.
src/daemon/sessionRegistry.ts (6)
1-6: LGTM!Imports are appropriate. Using
node:fs/promisesfor async operations andexistsSyncfor directory check is reasonable.
8-18: LGTM!The Zod schema is well-defined with appropriate constraints:
pidrequires positive integer- Required fields:
happySessionId,happyHomeDir,createdAt,updatedAt- Optional fields for extensibility:
flavor,startedBy,cwd,metadataUsing
z.any()formetadataallows flexible storage of session metadata.
32-36: Atomic write implementation is correct.Writing to a
.tmpfile and renaming provides atomicity on POSIX systems. This prevents partial writes from corrupting the marker file.
38-50: LGTM!
writeSessionMarkerproperly:
- Ensures directory exists
- Applies default timestamps
- Injects
happyHomeDirfrom configuration- Validates via Zod before writing
- Uses atomic write
52-59: LGTM!Silent catch in
removeSessionMarkeris appropriate - the marker may already be removed or never existed. The function is idempotent.
61-84: LGTM!
listSessionMarkershas robust error handling:
- Filters filenames by
pid-*.jsonpattern- Uses
safeParseto avoid throwing on invalid JSON- Logs parse failures for debugging
- Filters by
happyHomeDirfor cross-stack safety- Gracefully skips unreadable files
This ensures the daemon can recover even if some marker files are corrupted.

491-504: Useloggerinstead ofconsole.errorfor consistency.The codebase uses
loggerfor error logging throughout (e.g., lines 276, 293-294, 306). Usingconsole.errorhere is inconsistent and may bypass structured logging.♻️ Suggested fix

🔇 Additional comments (8)
src/persistence.ts (3)
9-11: LGTM!The additional imports (
mkdirSync,renameSync,dirname) properly support the new atomic write and directory creation functionality introduced in the persistence layer.
510-518: LGTM!The atomic write pattern (write to
.tmpthenrenameSync) is correctly implemented. Using synchronous operations here ensures atomicity and aligns with the docstring's intent. Therenameoperation is atomic on POSIX systems, preventing partial reads.
527-530: LGTM!Good addition to clean up leftover
.tmpfiles from interrupted atomic writes. The error swallowing via.catch(() => {})is appropriate for best-effort cleanup.src/daemon/run.ts (5)
20-20: LGTM!The import correctly brings in the session marker utilities needed for the reattachment feature.
177-204: LGTM!The reattachment logic is well-structured:
- Properly checks process liveness via
process.kill(pid, 0)- Cleans up stale markers for dead processes
- Avoids duplicates by checking
pidToTrackedSession.has()- Defense-in-depth
happyHomeDircheck (even thoughlistSessionMarkersalready filters)- Graceful error handling with try-catch
Based on learnings, this aligns with the requirement to track spawned Happy processes by storing their PID and happySessionId for cleanup purposes.
210-214: LGTM!Good cross-stack safety check. This ensures the daemon only tracks sessions for its own
happyHomeDir, preventing interference between different daemon instances or stacks.
252-260: LGTM!Best-effort marker write with fire-and-forget pattern is appropriate here. The session continues to function even if marker persistence fails—it just won't survive a daemon restart. The empty
.catch()correctly prevents unhandled promise rejections.
678-683: LGTM!Proper cleanup of session markers when child processes exit. The fire-and-forget pattern is appropriate for cleanup operations.

Compare
- Persist stack-scoped session markers (happyHomeDir + pid) so daemon can adopt still-running sessions on restart - Make daemon.state.json writes atomic (tmp + rename) and resilient (read retry); mkdir parent dir defensively - Keep daemon branch focused: no resume capability (that lives in resume-from-ui branches)
